The existence of a ‘multiplier’, ‘compositional’ or ‘social context effect’ is debated extensively in the literature on school effectiveness. Some researchers have posited that the relationship between social context and achievement is mediated by school, teacher or classroom factors, such as teacher expectations, quality of instruction, or adequacy of school resources. In this context, this…

Abstract This article proposes an innovative approach to evaluate firms’ inefficiency accounting for corporate social responsibility (CRS) activities of firms. In the first step, we estimate dynamic inefficiency for each input, marketable output, CSR output and investment using Data Envelopment Analysis. Dynamic inefficiency measure accounts for the confounding role of adjustment costs related with firms’…

This paper introduces a three-fold Fay-Herriot model with random effects at three hierarchical levels. Small area best linear unbiased predictors of linear indicators are derived from the new model and the corresponding mean squared errors are approximated and estimated analytically and by parametric bootstrap. The problem of influence analysis and model diagnostics is addressed by…

La investigación científica y la divulgación, esto es poner al alcance de un público más amplio son dos caras de una misma moneda, pero no es lo mismo. Entre los científicos y también entre los economistas encontramos a grandes investigadores que con el paso de los años también se han convertido en divulgadores muy populares…
Bullying is a widespread problem throughout the world that affects one in three students and whose consequences can last in the long term. The main objective of this research is to study the causal relationship between bullying and academic performance on 15-year-old students in Spain. The databases used come from the external evaluation of the…

Multivariate observations referring to parts of a whole, so-called compositions or compositional data in statistics, are common across varied scientific fields. This is for example the case when dealing with chemical concentrations, food nutritional contents, election vote shares, investment portfolios, time-use and behavioural patterns, relative abundances, amongst others. Their distinctive feature is that there is…

Abstract: This paper examines the role of LTC benefits on the use of primary and secondary care by exploring a detailed administrative database in Spain. We estimate the causal effect of receiving LTC benefits by exploiting exogenous variation in the leniency of the examiners who assess the claimants’ LTC needs. We find that a monthly LTC…

Este trabajo trata de determinar la conveniencia en el cambio de tecnología para la determinación de una enfermedad gastrointestinal. La determinación de la bacteria o virus que ataca al organismo puede ser determinante en las primeras horas, evitando posibles infecciones graves e incluso sepsis. Los dos procedimientos comparados son: (i) técnicas de cultivo estándar, utilizado…

Currently, information systems such as sensors produce a large amount of data, which is expected to experience exponential growth in the coming years. These data are often treated as time series, which are chronologically collected data representing a time-varying function. Time series appear in a wide range of scientific fields, such as hydrology, paleoclimatology or…

The Reduction of Emissions from Deforestation and forest Degradation (REDD) project was proposed and initiated in 2005. Monitoring of forest cover by statistical methodologies is a key pre-requisite. Forest cover is usually estimated at large scale by spatial sampling strategies, in which the study region is partitioned into polygons of equal size (e.g. quadrats). Then,…
